Abstract: A positioning device for hot stamping includes a pilot pin and a driving mechanism for driving the pilot pin. Before a plate material is placed into a press die, when the driving mechanism positions the pilot pin at a predetermined projecting position, a tip portion of the pilot pin projects from a pin guide hole and a body portion of the pilot pin formed further toward a base end side than the tip portion projects from the pin guide hole. Before a process in which the press die removes heat from the plate material after having been press-formed by the press die, when the driving mechanism positions the pilot pin at a predetermined immersed position, the body portion of the pilot pin is immersed in the pin guide hole while only the tip portion of the pilot pin projects from the pin guide hole.

Abstract: A surface shape of a machining surface of a rotating elastic grindstone is rendered to be a shape appropriate to a to-be-machined surface of a work. With the work being rotated, the rotating elastic grindstone is held in engagement to an end of the to-be-machined surface of the work. The elastic grindstone is moved along a machining trajectory effective to allow the machining surface of the elastic grindstone, which is so formed as to suit to the to-be-machined surface, to follow the to-be-machined surface of the work. The to-be-machined surface of the work so superfinished represents a smooth surface free from any machining trace such as a crossing-angle pattern.

Abstract: A method for testing a magnetic recording medium includes positioning second magnetic heads in an inspected region of a testing subject medium based on servo information signals. A signal generating step generates a magnetic recording/reproducing signal by making the second magnetic heads to conduct a magnetic recording/reproducing process of the inspected region. A signal processing step inspects the magnetic recording/reproducing signal. A master medium includes a servo information region where servo information is recorded radially from the center in a continuous manner. The inspected region corresponds to regions in the master medium including two or more data information regions adjacent to each other in the same track position via the servo information region. The position of one of the inspected regions in the radial direction is arranged at a different position from that of another of the adjacent inspected regions arranged at a different track position.
